- From several sources I've heard that PCP is making a reappearence on
- the drug scene.
-
- I have some excerts from _Clinical_Management_of_Poisoning_and_Drug_
- Overdose by Haddad Winchester. A thourghly excellent reference,
- with very few errors, those errors that I have found (only one) is
- understandable due to lack of information at the time of printing.
-
- Chapter 33 Phencyclidine (PCP) written by Toby L. Litovitz, M.D. pg. 448-455
-
- .. History of PCP as a anesthetic, but that it produced psychotic reactions
- in 15 to 20 percent of patients for 3 to 18 hours.
- Then a short history of its debut in San Francisco as PeaCe Pill and Hog.
-
- ... Now back to the text:
-
- In the early 1970s, phencyclidine reappeared on the streets, this time as a
- drug of deceit. Since it was easily and cheaply synthesized in clandestine
- "kitchen" laboratories without the risk of illegal importation, it was
- frequently substituted for and sold on the street as THC, cannabinol,
- mescaline, psilocybin, LSD, amphetamine, cocaine, Hawaiian woodrose, and
- other psychedelics. In fact, in one study only 3 per cent of analyzed street
- drug samples that contined PCP were actually sold as PCP. THC, which actually
- is not available on the street, was the most frequent misrepresenatation.
-
- .... More text on it's use through the 70s ...
-
- Considerable conflicting evidence exists in the literature regarding the
- mechanism of action of phencyclidine. Phencyclidine is thought to stimulate
- alpha-adrenergic receptors and to potentiate the pressor response to
- epinephrine, norepinephrine, and serotonin. Other studies have shown
- phencyclidine to have brief low level anticholinergic activity during the
- intial phase of intoxication. Phencyclidine is also thought to inhibit
- acetyl- and butyryl-cholinesterase. Others postulate that phencyclidine may
- act on opiate receptors.
-
- Phencyclidine abusers feel the onset of drug effect in 2 to 5 minutes when it
- is smoked, compared with 30 to 60 minutes when ingested orally. The peak
- effect is reached in 15 to 30 minutes after smoking the drug and abusers
- report that they stay "loaded" for 4 to 6 hours, then feel normal in 24 to
- 48 hours.
-
- ...
-
- PCC (1-piperidinocyclohexanecarbonitrile) appears in poorly synthesized
- batches as a by-product of the manufacturing process. When present in
- significant amounts (10 to 25 per cent), this contaminant causes
- abdominal cramps, bloody emesis, diarrhea, and coma. PCC is an unstable
- compound, degrading to piperidine. As a result, contaminated batches of
- PCP can sometimes be recognized by the strong fishy odor of piperidine.
- On heating (smoking), PCC liberates hydrogen cyanide, so the possibility
- of cyanide poisoning in PCP smokers should also be considered.
-
- ..
-
- Patients ingesting small amounts of phencyclidine present prominent
- body image distortions (enlarging limbs, detached head) on a background
- of sensory blockade described as a "numbness", depersonalization,
- "sheer nothingness" or "endless isolation". These patients feel inebriated,
- are usually disoriented, and sometimes have amnesia for the experience.
- Somatic sensation is dissociated: patients lose track of their bodies and
- are at risk of seriously injuring themselves because they do not perceive
- pain. Though visual, auditory, and tactile illusions and delusions (especially
- of being God, the devil, or an animal) are common, frank hallucinations are
- relatively uncommon when compared with those produced by LSD. Anxiety
- and, sometimes, outright hostility may be present. Disrobing in public
- is seen in a small percentage of patients. Perhaps the hallmark of PCP
- intoxication is the recurring delusion of superhuman strength and
- invulnerability resulting from the analgesic and dissociative properties of
- the drug. Intoxicated patients have been known to snap hancuffs and, unarmed,
- attack, large groups of people or police officers. This loss of fear has
- led patients to try to stop a train by standing in front of it, to grossly
- mutilate themselves and others, to climb into a polar bear's cave to take
- a picture, and to jump from windows or cliffs. The bizarre behavior is often
- violent, sometimes with gruesome mutilation of both the patient and his
- or her victim. One intoxicated abuser pulled out his front teeth with a
- pair of pliers. Another woman fried her baby in cooking oil. There are many
- reported assaults of friends and strangers, both with and without weapons.
- Many of these violent acts are committed by drug users who were
- previously totally nonviolent individuals.
-
- ...
- Note from Me: this is refering to moderate to high doses in the preceeding
- paragraph
- ...
-
- Patients with moderate or high dose intoxications are intially comatose. Those
- with moderate-dose intoxications have a relatively short duration of coma
- (several hours) compared with the prolonged coma associated with higher-dose
- exposures (usually lasting 6 hours to several days but occasionally persisting
- as long as 10 days).
-
- ... Much technical medical data deleted here ...
-
- Mildly intoxicated patients are best treated with sensory isolation in a
- nonthreatening environment on a cushioned surface in a darked, quiet room,
- without neglecting the need for frequent monitoring of vital signs.
- Instrumentation should be avoided.
- ...
- The techniques of "talking down" as advocated for most hallucinogens are
- ineffective for PCP and may instead further agitate patients.
-
- .. Medical data about higher doses and effective means of sedation ...
-
- -----
- My notes follow
-
- Woah! Sounds damn bad. Highly not recommended, be careful this stuff
- is rarely sold for what it is. It is making another round right now.
- This is the kind of stuff that fuel prohibitionists, avoid it, tell
- others and spread the word. Print this out and distribute it. It
- is not just propaganda, the source of this information is highly
- reliable.
-
- Read it and believe it.

- >What a crock of shit. Where did you get this "reliable" book, the PDFA?
-
- While I don't believe that PCP (or any other drug for that matter, except
- maybe alcohol (just kidding)) is an "evil" drug, I believe there is evidence
- to show that a PCP trip in a naive user can be a very frightening thing.
- Although the text in question may have shown the extreme to the absence
- of the normal PCP "trip", I think this is only natural since the only
- "trips" which would have become relevant to law enforcement would be
- precisely those which were extreme. Sorta like the phenomenon that the
- most nutty segments of a group (e.g., televangelists of Christians) tend
- to be the most noticed.
-
- Some things to consider:
-
- -- PCP is not necessarily more likely to lead to criminal behaviour than
- other drugs, and in fact some studes (sorry I don't have references for
- this one, it's been awhile) show that PCP-intoxicated users are less
- likely to pose a threat to law enforcement than alcohol-intoxicated
- users.
- -- PCP does, however, have a fairly high rate of inducing "bad trips" in
- users who are naive to its effects, and/or not expecting them. I know
- several people who *have* obtained PCP laced MJ, occasionally without
- knowing it (this based on a friend who is experienced with PCP, and
- sampled the material in question). Furthermore, in some areas PCP is
- not particularly expensive, and PCP-MJ combinations do tend to show
- up and be about the same cost as "kind" (e.g., $50 to $75 per quarter
- ounce). This is regional; YMMV. Yes, this is a shitty thing to do to
- someone, but sometimes it was unintentional (e.g., friend A "borrows"
- some of friend B's dope, and sells it to friends C, D, and E). Which
- just goes to show, know your source.
- -- In particular, most people who aren't expecting a dissociative
- anaesthetic can get *quite* disturbed by the experience. Many people
- find it unpleasantly reminiscent of fever dreams. That, coupled with
- the lack of feedback from sensory and muscle input, can be a dangerous
- combination simply because people can injure themselves and not know
- it.
- -- PCP shares with alcohol certain effects on ion channels (in particular
- NMDA), and some of alcohol's "inhibition releasing" effects may be
- NMDA related as opposed to GABA related. Any drug capable of reducing
- inhibitions can be undesirable in people not particularly comfortable
- with themselves.
- -- PCP's pharmacology (as well as that of ketamine and dizocilpine, and
- to a lesser extent dextromethorphan and noscapine) is unique in that
- it affects a set of receptors whose role seems to be much more involved
- in "ordinary" neurotransmission (*), i.e. the NMDA receptor. Contrast
- with the indolealkylamines (e.g., LSD), phenylalkylamines, etc., which
- primarily affect "regulatory" neurotransmitter systems -- 5HT, dopamine,
- and noradrenaline.
- -- People expecting to "wig out" on PCP are likely to do so, regardless of
- whether they would have absent from the expectations.
-
- * Actually the NMDA receptors are involved in long-term potention, but
- I think there's evidence that LTP is involved in more than just
- hippocampal short-term memory encoding. If nothing else, people with
- no hippocampi don't show sensory blockade like NMDA antagonists
- produce. In any case NMDA neurotransmission is widespread and
- ordinary.
-
- In general, although I have not taken PCP myself, I tend to agree that it
- is not something to be entered lightly. *MANY PEOPLE REACT POORLY TO
- DISSOCIATIVE ANAESTHETICS* If you don't like the idea of being "out of
- touch" with your body, feeling cut off from reality like that, it's not
- for you.
